4. For Proposal Name, type a descriptive string of 1 to 32 alphanumeric
characters. The string must be unique to this proposal.
Often, it is a good idea to indicate the algorithms that you will select in
the name—for example, ESP3desMD5.
5. For Encapsulation Mode, typically select Transport Mode.
This is the correct mode for this type of VPN because the TMS zl Module
and the remote tunnel endpoint originate all of the GRE traffic.
6. For Security Protocol, select AH or ESP.
